Application filed name;

bumpers being yieldable into alin'e'ment with the usual spare tire before the fenders or.

accessory devices are reached. Thus the tire provides anv unyielding resistance to the front bumper of the colliding car after the maximum desirable yielding of the wing bumpers has taken place.

Another feature of the invention relates to a novel wing bumper which is well adapted for use as described above, and whichis shown as comprising vertically-spaced impact bars pivotally connected to a resilient supporting bar secured to the chassis frame. Other objects and features of the inven tion, including various novel combinations of parts and desirable particular constructions, will be apparent fromthe following description of the illustrative embodiments shown in the accompanying drawings, in.

obstructing. the spare tire, the lights, the.

- gasoline tank, or the trunk which is often arranged between the spare tire and the car body. In the form shown in Figs. 1, 2, 3,- 6 and 7, each. wing bumper comprises rertieally-spaced impact bars 22 and 2t, pivotally connected by shackle bolts 26 to the outer ends of supporting bars 28 and 30. The ends of the bars 22 and 2-1, and the outer ends of the bars 28 and 80, are formed as eyes enibracing the connecting shackle bolts 26.

The adjacent ends of the supporting bars' 28 and 30 are superposed, and are secured by bolts 32 to the downwardly curved ends of the side frame members 10.

As best shown in Figs. 6 and 7, the bumpers are so arranged that in case of a rear end collision with a following car 3% having a front bumper 36, thewing bumpers will first yield. to the maximum desirable extent, -whereupon the front bumper 36 will engage the rigidly supported 'tire.18,-v\'hich thus '-ser'ves effectively to limit yielding of the bumpers before any damage is done to the fenders 12 and 1a, and which also protects lights 20 against damage.

In the modification shown in Fig. 4, the impact bars 122 and 124: are connected. at their outer ends by a shackle bolt 126 to a single supportin bar 128, and at their in ner ends are connected thereto by asecondw my invention have been described in detail,

the frame, side fenders,

it is not my intention to limit its scope to those embodiments,or otherwise than by the terms of the appended claim.

I claim: h

A vehiclerhaving", in Combination, a chass s frame, a support for a spare tire carried by and wing bumpers carried by the frame on opposite sides of the support in position to protect the fenders, the'bumpers being pivotal y supported from theframe at points in front of the vertical plane of the rear face of the tire, and extending rearwarclly of the tire to take the first impact of the front bumper of a fol1o\v. ing car, saicl' bumpers being yieldable into alinemen-t With the rear face of the tire so that excessive force in case of a rear end col-- Iision is transmitted to the frame through the tire support before the bumpers are bent into engagement with the fenders.

In testimony whereof I afiix my si nature.
